Does this setup contravene any regs or is it ok?

You cannot comply with BS7671 by bunching circuits such as lighting or radials in the same OCPD. It is non compliant.

Disagree

And if you make this a ruling my crystal ball sees lots of wago's or choc block used within DB's - so only 1 cable runs to the OCPD

Daft.

A fridge in no way satisfies any definition of a circuit. It defines a piece of current using equipment fed by a circuit.

It’s an assebly of electrical equipment protected at it’s origin by an OCPD.
How does that differ from the definition of a circuit?

I presume you are talking about my posts. I am not shouting. I have explained my argument numerous times to the point of being immensely frustrated.

My argument has never been about whether lumping circuits together is safe; indeed I have admitted that I have done it, albeit for a temporary stop gap solution. It may well be electrically safe and in which case it can be done (temporarily).

If it is done as a new install it should be highlighted in the EIC as a non compliance and explained as to why it was done, along the lines of a justification. (By the way, the excuse of ‘I needed another spare way because I didn’t buy a big enough CU, and don’t think that the two I have looks to be enough for possibly future expansion’ is not a justification in my view).

If it is found during an EICR it should be highlighted as a C3 or a C2 if it proposes an electrical risk.

How much clearer can I be?

If you guys still don’t agree now then I can only assume that you have been practicing this. I haven’t so I’m not bothered by it.

I will now bow out! Live long and prosper!

I fail to see why it poses an Electrical risk? Could you eleaborate on why?

True, only thing is you're using the bs7671 definition but that only applies to fixed wiring. Make it an fcu and I'll agree

By your definition my electric razor is a circuit. And a gu10 lamp.

just to be an a**e they are... they are electronic circuits (assuming the GU10 is an LED)

My example was halogen. So there

Not my definition, and no, neither of those items.
A toaster perhaps, or a kettle.

The definition of a circuit, makes no reference to fixed wiring.

So a toaster is a circuit but not an electric razor. I really don't get this definition of circuit you are using.

Does your electric razor have a fused plug?

 

[DPG]

It's an appliance. It is current using equipment. Just like a table lamp or a fridge freezer, or anything that plugs into a 13A socket. It is NOT a circuit.

I’m glad that we have established that something that satisfies a definition in BS7671 is not necessarily the thing being defined.
So does this mean you are stating 2 circuits connected to the same MCB are 2 circuits or 1?

At risk of adding to the fire, App 15 Fig 15A in BBB states that "an infused spur may be connected to the origin of the circuit in the distribution board". Which to me says the origin of circuits is the distribution board (no toasters need apply, sorry) and a circuit may branch from within the board.
